We did not observe any elevated frequency of studied SNPs polymorphic variants correlating with cigarette smoking among LC patients in any of investigated cases.
The frequency of studied allelic polymorphism among cases was compared to that of controls describing number and percent of each and tested for positive association using Fisher's exact test and odds ratio (OR) with 95% confidence intervals (CI).
Results: Genotype and allele frequencies of studied polymorphisms in cases of overweight/obesity showed no significant statistical difference compared to that of controls.
The data showed no statistically significant difference between the elderly and young groups when comparing genotypic distributions and allelic frequencies of studied SOD2 and MTHFR polymorphisms (Table 1).
In another study, Kuittinen, and Meriläinen (2014) investigated the frequency of study‐related burnout with respect to student motivation and students' perceptions regarding learning environment.
The same criteria - the frequency of study - was also used for the evaluation of Key Performance Themes for sustainable railways, also identified during the review.
This extensive work reflects in the increase in the frequency of studies from 1990 into the early 2000's, as shown in Fig. 5.
In contrast to the frequency of studies on root resorption after orthodontic treatment, those focussing on reductions in the marginal bone heights are rare.
Some trials have attempted to replicate real-world conditions in their choice of inclusion/exclusion criteria, use of placebo, frequency of study visits, and lithium monitoring (Geddes et al. [2010]).
The primary safety endpoint was the frequency of study events; study events were distributed across all treatment groups.
Twice each day, frequency of study drug administration was adjusted according to delirium status, level of sedation, and side effects.
